Writing well doesn't mean you're smart, it just means you've put some effort into writing well. It's an exercise in empathy and consideration for one's readers, and crafting tolerable sentences with reasonably-normal usage is just the start of it. Ensuring you're writing something worth reading, with every sentence and every word, is another. "Bullshit written by ignorants" tautologically falls short of that, however fit their writing is otherwise.
